Title: Seat cushion
Inventor: NAGASAWA YOICHI
IPC: A47C31/11
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent a frame and a pad of a seat from slipping in the process of manufacture or in the repetition of getting on/off. SOLUTION: A seat cushion pad 13 is assembled to the seat cushion frame 11 by inserting center legs 17 and left/right side legs 18 into corresponding center slits 23 and left/right side slits 24. The center slits are formed in one half-folded side 25 of a band-shaped hanging cloth 14, which can be folded in two in the width direction, corresponding to the legs 17 and 18 of a hang-up wire 12. The one half-folded side 25 is joined by integral foaming to the surface 22 of the pad rear 21 of the seat cushion pad with the fold back part 27 above. The band-shaped hanging cloth 14 wraps the hang-up wire 12 in the other half- folded side 26 of the two-folded cloth with the legs 17 of the hang-up wire being inserted into the corresponding slits as the seat cushion pad is assembled to the seat cushion frame.

Title: Method and device for mixing multiphase fluids
Inventor: YOKOMIZO TOSHIO
IPC: B01F5/00
Filed: 1999-12-06
Abstract: PROBLEM TO BE SOLVED: To mix fluids very different in density without generating a gyrating current in the downstream part by making bubbles into minute ones with small pressure loss and homogenizing them. SOLUTION: Two-phase fluids, gas and liquid, are made to pass through a static mixer part 4 at first to mix them more roughly and then through a twisted fin-bundled part 6 made by bundling plural twisted fin elements 7, each of which is obtained by twisting a strip of a plate, without superposing one on another to cover the whole cross section of a pipe. Liquid is pushed upward and gas is pushed downward to mix them vertically by a static mixer element 5(1) being the first step of the part 4 and they are mixed horizontally by a static mixer element 5(2), whose phase is lagged by 90 deg., being the second step. The elements 7 of the part 6 give a rotary motion to the liquid and gas by making them flow along the elements 7 and generate shearing force so that the bubbles are made into minute ones.  The turning flow is restrained from generating by the symmetric arrangement of the elements 7.

Title: Exposure device
Inventor: YAMADA MAKOTO
IPC: G03F1/00
Filed: 1992-12-25
Abstract: PURPOSE:To provide an exposure device in which the production cost of a mask and mask exchanging time are reduced and whose processing ability is high by using a light shielding means including a liquid crystal display element. CONSTITUTION:A wiring pattern stored in a pattern storage circuit is displayed on the mask 11 constituted to include the liquid crystal display element by a control circuit.

Title: Document preparing device
Inventor: KINOSHITA JUNICHI
IPC: G06F17/21
Filed: 1993-12-28
Abstract: PURPOSE:To prevent the insignificant printing errors by eliminating the waiting time of work and the troublesome operations which are caused when plural documents are sequentially designated for printing. CONSTITUTION:The format information on a desired document is designated for printing in step 12 under the document printing conditions. Then this format information is evolved in step 13 into a print information management file by a print information management file register function. Thus the desired documents to be printed are repetitively designated in step 12. The documents are divided into groups by a document setting function in step 15 based on the same format information on the designated documents. The titles and the format information on those groups of documents are shown on a display device 2. Then a print key is pushed in step 16 and plural print functions start in step 17. Thus the groups of documents are automatically and successively outputted. Then the documents are printed in step 18 and sorted by the types of forms, and these sorted documents are outputted.
